DIY Cruise Control FAQ (2006-2010 Yaris)

[abarson]

I bought the stalk for my '10 sedan on ebay, but the car got wrecked before I installed it.
I've got a '12 sedan AT, with what seems to be a partial Power Package (windows only, not locks, etc.). I'm assuming that the stalk is the same? Any idea what the wiring requirements are for this year/model?

I've also read the tutorial multiple times, but remain a bit confused about D3. I get that there are supposed to be 3 wires in it-one of them being ground and two that are added-but where is the other end of the wires?

The stalk is the same for '10 and '12.

Did you look at your D3 connector yet? If you have the three wires there, then you just need to install the stalk. If you do not, then one goes to ground and the other to the ECM connector. See my complete DIY below for details:

It works! Took an hour only because the horn wire broke. D3 was already wired, although the block looks different on the 2012.
Thanks so much for posting this tutorial!

Thank you so much for this thread! I have a Base Yaris which could benefit from CC.

CTScott, Do you still sell the switch and wires needed to do this modification?

Yes. I still have all of the cruise control parts available.

Hi there would anybody be able to tell me if my T3 Yaris will support cruise control? It is a south African spec. I am not sure if i will need a cruise control module?
Or, how can i check if it has

What year is it and which engine does it have?

I was going to say no, but looking at the specs for some T3's it looks like cruise was an option. Take a look at my DIY (linked under my signature picture). To be sure, start with checking for the presence of the connector D3 wires on the steering column, and if they are not present check for the presence of the pin 40 wire on the ECM. Finally, if that is not present, check for 12V to be present on that pin with the ignition in the on position.

there is D3 when I earth the blue wire there is no icon(assuming that it may be because there is no space on the cluster for that light?) there is no pin in 40 on ECM plug... btw the D3 has more than just a black wire out of it, it ahs a brown and blue, however they are not in the specified places

OK. By the wires present it looks like you have steering wheel audio controls (or at least you car is wired for it).

So, the next test is measuring the voltage on the ECM pin 40. You can pull the rubber plug and stick a piece of wire in there to take the measurement.

Hi ÇTscott, can i pull the ECM plug off with the battery connected? Btw on the plug side there is no wire coming from pin 40 of the plug

Yes - You can pull it with the battery connected.

You will need to pull out the little rubber hole plug (easiest way is to stick a sewing pin into the hole and push the plug out the back side). Once the plug is out you can plug the connector back in and stick a small piece of wire into the hole to make contact with the ECM pin. Then, turn the key to the ON position and measure the voltage on that pin.

OK awesome, will try that and let you know?

BTW I did read the DIY section when i first started, wasn't sure how to check if there were preparations for the cruise control already ion place, but now i know, thanks a ton, will let you know what the result is

Hi CTscott

I have tried to place a led light in there, i earthed the one side and shoved the + side in the whole, it did not come on...

must i try it with the + side on battery and shove the - side in there? The reason i am using the LED because i dont have a meter hereXD

oops double post:)

I have tried the + and - and cant get the light to shine:(

Oh well at least I tried... Now it is time for me to find a suitable cc for my Yaris. If anyone has any sudgestions let me know, Thanks a mil
